Senior Data Engineer; AI Ingestion Platform

We are Software Mind, an awesome team of engineers who are ready to ramp up any top‑notch company’s projects! Our aim? To always be one step ahead. Become part of a multicultural company in constant growth with an excellent work environment certified by Great Place To Work.

Software Mind is building a private, tenant‑isolated AI assistant for the real estate title and settlement industry. The platform is a retrieval‑first (RAG) system that ingests historical email, documents, and structured metadata into a per‑tenant vector index, and serves grounded, cited, expert‑weighted answers through a chat‑style Q&A interface with single sign‑on and full audit logging.

The platform is AWS‑native with a Python/FastAPI backend, Vue.js frontend, Open Search/Pinecone vector store, and OpenAI/Anthropic/Bedrock as LLM provider. You will join a senior, cross‑functional LATAM‑based team where hands‑on AI delivery experience, not just familiarity, is the baseline expectation.

You own the ingestion and processing backbone of the platform: the pipelines that transform raw email and document corpora into clean, PII‑minimised, chunked, and indexed data in the per‑tenant vector store. This is the foundational layer the AI extraction gateway depends on; quality here directly determines system accuracy.

• Build and own the historical email ingestion pipeline via Microsoft Graph API.
• Implement SharePoint / One Drive document ingestion pipeline with scoped folder access.
• Design and implement the PII minimisation pre‑processing layer.
• Build the vector store indexing workflow (Open Search/Pinecone) with per‑tenant data isolation.
• Define and implement the data processing schema; produce and maintain schema documentation.
• Build the OCR routing orchestrator and integrate OCR service for scanned documents.
• Implement the raw text / content extraction layer for all supported document types.
• Define and prototype push vs. pull ingestion strategy, from one‑time PoC through to incremental nightly pipeline.
• Ensure data lineage and audit traceability are built into pipeline outputs from the outset.
• Tech Stack:
  Python, Microsoft Graph API, AWS (S3, DynamoDB, Lambda), Open Search, Pinecone, OCR Tooling, PII Libraries, NER Libraries, Docker, Jira, Confluence.

• 6+ years in data engineering; strong pipeline and ETL/ELT experience required.
• Proficiency in Python for data pipeline development.
• Experience with Microsoft Graph API or similar enterprise email/document APIs (M365, Exchange Online).
• AWS data services: S3, DynamoDB, Glue, and/or Lambda‑based event‑driven processing.
• Familiarity with PII detection and data minimisation techniques (regex‑based, NER‑based, or purpose‑built libraries).
• Experience with vector store indexing or semantic search pipeline construction.

• Prior experience building ingestion pipelines specifically for AI/ML, NLP, or LLM‑based platforms.
• OCR tooling experience: AWS Textract, Tesseract, or commercial OCR services.
• Understanding of per‑tenant data isolation patterns, tenant‑scoped encryption, and row‑level security.
• Familiarity with Lang Chain document loaders, embedding pipelines, or vector index management.

We are accepting applications from LATAM countries.
